 note = {P(論文), Metamorphic and plutonic rocks from the Belgica Mountains, East Antarctica, have been geochemically examined to evaluate original rock types and petrogenesis. Trace element compositions on 16 samples from the Belgica Mountains and 4 samples from the Yamato Mountains were determined with an X-ray fluorescence spectrometer. High concentrations of Ba, Rb and Sr with very low levels of Nb, P and Y were found on granitic gneisses. The chemical feature is considered to represent the result of in situ partial melting. Basic and intermediate metamorphic rocks show variable compositions. Some of the rocks have slight enrichment of LIL elements with distinct Nb depletion. The chemical characteristics indicate that the rocks were generated probably under subduction environment. Syenitic rocks from the Belgica Mountains and gneisses from the Yamato Mountains are extremely enriched in Ba, Rb, Sr and Zr. Enriched source must be considered for the generation of the syenitic magma.},
